Abstract: 1,133,123. Working rubber. RHONE-POULENC, S.A. 9 March, 1966 [10 March, 1965], No. 10420/66. Heading B1C. [Also in Division C3] Rubber and additives are mixed by counterrotating rolls 1, 3, the roll 1 rotating at the slower speed so that a sheet of rubber forms round it. From the sheet is cut by disc cutters 7, 8 a strip 9 which is carried over guide rollers 10, 11 and returned to the roll nip at a different axial position from that at which it was removed. The guide rollers 10, 11 are parallel to each other but at an adjustable angle to the rolls 1, 3; the roller 11 is driven. The disc cutters 7, 8 can be adjusted along their shaft and the angle of the guide rolls altered to vary the locations of removal and return of the strip 9; this may be done automatically. In another embodiment (Figs. 3 and 4, not shown), two strips are cut from the ends of the rolls and returned together to the centre.

Patent GB-417936-A (GB)
Title: Improvements in the manufacture and production of carboxylic acid arylides
Filed: 1933-04-10
Abstract: Aromatic carboxy-arylides are prepared by condensing aromatic carboxylic acids or their anhydrides, halides and esters with aromatic primary or secondary amines containing at least one enolisable group capable of being coupled.  The first component should be free from enolisable groups, whilst the enolisable group of the second component is attached to the nucleus substituted by the amino group.  Enolisable groups mentioned are --CO.CH2.CO.CH3, --CO.CH2.CO.NHR (in which R is alkyl, aryl &c.), --NH.CO.CH2.CO.CH3, and the radicle of 5 - pyrazolone.  The reaction is preferably effected by heating in solution in the presence of acid condensing agents such as phosphorus trichloride.  The products have a good affinity for vegetable fibres and are capable of being coupled with one molecular proportion of a diazo compound in the enolisable group and with a further molecular proportion of a diazo compound if the carboxylic acid used contains a coupling position.  Examples are given of the condensation of (1) 2 : 3-hydroxynaphthoic acid and its chloride with p-aminobenzoylacetic acid anilide; 2 : 3-hydroxyanthracene carboxylic acid or 2 : 3-hydroxycarbazole carboxylic acid may replace the acid component; (2) 2 : 3-hydroxynaphthoic acid chloride with 1-(p-aminophenyl) - 3 - methyl - 5 - pyrazolone; (3) benzoyl chloride or m- or p-nitrobenzoyl chloride with p-aminobenzoylacetic acid anilide; (4) 2 : 3-hydroxynaphthoic acid or its chloride with m p  - aminobenzoylacetic acid -2 : 4-dimethoxy-5-chloranilide; (5) 2 : 3-hydroxynaphthoyl chloride with acetoacetic acid -m-aminoanilide, acetoacetic acid -p-aminoanilide or acetoacetic acid -p-methylaminoanilide.  The presence of alkoxy and halogen groups in the acid component is also referred to. Anilides.--p-Aminobenzoylacetic acid anilide is prepared by condensing p-nitrobenzoylacetic acid ethyl ester with aniline and reducing the product.  m-Aminobenzoylacetic acid -2 : 4-dimethoxy-5-chloranilide is similarly obtained by reducing the condensation product of m-nitrobenzoylacetic ester and 2 : 4-dimethoxy-5-chloraniline.  Acetoacetic acid -m or p-aminoanilide is prepared by reducing the corresponding nitro body.  Acetoacetic acid -p-methylaminoanilide results from the condensation of p-N-methylaminoaniline with acetoacetic acid ethyl ester.
